Three-petal type stator assembly of wind driven generator of 12MW and above

Abstract

The invention discloses a three-petal type stator assembly of a 12MW and above wind driven generator, which comprises a fixed sleeve, three stator fixing plates are arranged on the periphery in the fixed sleeve, positioning driving plates are arranged on the rear sides of the stator fixing plates, the stator fixing plates are completely the same in structure, and the positioning driving plates are arranged on the rear sides of the stator fixing plates. The bottom end of the inner cavity of the stator fixing plate at the bottom end and the inner cavity of the fixing sleeve are provided with a compression-resistant protection anti-fault mechanism. When the positioning driving plate is connected with the outside for use, a screw penetrates through the interior of a fixing pin opening, one side of the screw makes contact with the front side of an extrusion ring, the extrusion ring is pushed to move towards the interior of a mounting ring opening, an extrusion spring is extruded through the extrusion ring, and the extrusion ring is pushed to move towards the side away from the mounting ring opening through the reaction of the extrusion spring; and the firmness and the friction force between the screw and the interior of the fixed pin opening can be increased, and the problems of falling damage and safety caused by loosening and falling of the screw after long-time working in the using process are prevented.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a three-lobe stator assembly for wind power generators of 12MW and above. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. It is composed of components such as a speed safety mechanism and an energy storage device, especially the large megawatt stator assembly of 12MW and above. Due to its huge size when in use, there will be safety problems when it is subjected to external shocks and the staff cannot find it in time. The situation of hidden dangers, and it is easy to cause safety accidents in the later use. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a three-lobe stator assembly for wind turbines of 12MW and above, so as to solve the problems raised in the above background art. [0004] In order ...

AI Technical Summary

Problems solved by technology

[0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. A wind turbine generally includes a wind wheel, a generator (including devices), a steering device (tail), a tower, and a limiter. Composed of components such as high-speed safety mechanism and energy storage device, especially the large-megawatt stator assembly of 12MW and above, due to its huge volume when in use, there will be a safety hazard when the staff cannot find it in time when it is impacted by the outside. Hidden dangers, and it is easy to cause safety accidents in later use
